Washer depressions or protrusions on the slot faces used to help secure the old wheel may prevent the nut from sitting flatly against the surface of the slots. A flat surface is mandatory and any depressions or protrusions must be filled or bridged (not filed away) on both sides of the hub. On the wired side of the hub a “U” shaped washer must be used. You can fabricate one by removing a 1/4 or 1/3 section from a regular washer having an inside diameter equal to the width of the axle between the flats with a thickness slightly greater than the depth of the depression or height of the protrusion. If you posses sufficient electrical skill you can cut and splice the hub motor wires at the connector end so uncut washers can slide over the wire first and then the axle. Skill in splicing, soldering and covering each splice with heat shrink tubing is required and may void the warranty if not done right. In some cases only cut washers can be used to compensate for depression size or protrusion location.

A 2/3 washer is used here to compensate for both the protrusions and the washer depression. Place enough washers on the axle inside the forks so the forks do not touch the hub or to match the existing width between the forks.
